这是我的容器组件（DashboardComponent）HTML，用于显示列表：
<div class="ui bim-container stackable three column grid">
<div class="column">
<be-ui-list title="PROJECT" type="image" create="true" [items$]="projectItems" itemLimit="6"></be-ui-list>
</div>
<div class="column">
<be-ui-list title="FEED" type="flat" [items$]="projectItems" itemLimit="6"></be-ui-list>
</div>
<div class="column">
<div class="ui segment">
<be-ui-loader [show]="!user"></be-ui-loader>
<div>USER INFORMATION</div>
<div class="ui divider"></div>
<div class="ui fluid">
<div class="content">
<a href="javascript:;"><img class="right floated tiny ui image" src="{{user?.avatar?.src}}"></a>
<h4>{{user?.name}}</h4>
<div class="meta">
<small>{{user?.role}}</small>
<br> <small>{{user?.since | date:'medium'}}</small>
</div>
</div>
</div>
</div>
</div>
</div>
这是顶级组件：
@Component({
directives: [<Type>UILoaderComponent, (forwardRef(() => UIImageListComponent)), (forwardRef(() => UIFlatListComponent)), FORM_DIRECTIVES],
pipes: [<Type>IsArrayNullPipe, <Type>ArrayCountFilterPipe, <Type>ArraySortPipe, <Type>ArrayFilterPipe],
selector: "be-ui-list",
template: `<div class="ui segment">
<be-ui-loader [show]="!(items$ | async | beIsArrayNull)"></be-ui-loader>
<div>
{{title}}
<a *ngIf="create" href="#/project/create" class="ui right floated teal right labeled icon button mini">
<i class="right add icon"></i>
Create project
</a>
</div>
<div class="ui divider"></div>
<div *ngIf="(items$ | async | beIsArrayNull)" class="ui fluid icon input {{loadingClass}}">
<input type="text" [ngFormControl]="searchBox" (keyup)="onKeyUp($event)" placeholder="Search...">
<i class="search icon"></i>
</div>
<div class="error" *ngIf="((items$ | async
| beArrayFilter:[search, 'text']
| beArrayCountFilter:itemLimit)?.length == 0) && (items$ | async | beIsArrayNull)">
Your search yielded no results.
</div>
<div [ngSwitch]="type">
<be-ui-image-list *ngSwitchWhen="'image'"></be-ui-image-list>
<be-ui-flat-list *ngSwitchWhen="'flat'"></be-ui-flat-list>
</div>
</div>`
})
export class UIListComponent implements OnInit {
@Input("items$") items$: Observable<Array<{}>>;
@Input("title") title: string;
@Input("itemLimit") protected itemLimit: number;
@Input("type") type: string;
@Input("create") create: boolean;
protected searchBox: Control = new Control();
protected maxItems: number;
protected loadingClass: string;
protected currentItemCountLimit: number = config.itemCountDesktop;
protected search: string;
constructor() {
this.searchBox.valueChanges
.debounceTime(400)
.distinctUntilChanged()
.map((text: string) => encodeURI(text.trim()))
.subscribe((text: string) => {
this.search = text;
this.loadingClass = "";
});
}
ngOnInit(): void {
this.items$.subscribe((items: Array<{}>) => this.maxItems = items.length);
}
onKeyUp(event: KeyboardEvent): void {
this.loadingClass = "loading";
}
}
我省略了派生类，因为它们仅在html中有所不同。
这是什么问题？我应该提一下，这曾经没有类继承，但我重构了它，因为它有很多共同点。
